GOVERNOR OR' sieren-REGULATOR..

Specification of Letters Patent. Patented Steph. '7, 1999. Applicationfiled February 9, 1909. Serial No. 476,917.

To all whom t may concern Be it known that we, ALBERT DE DION andGEORGES BOUTON, citizens of the French Re-4 proved form of centrifugalpump, acting as a speed governor for the engine by which it is operated.

The invention also aims to provide a device of this kind which isparticularly ap,` plicable to explosion engines, in which case itperforms the double function of causing the water circulation, andacting as the gov* ernor or speed regulator of the engine.

Tn the accompanying drawing Figure 1 is a longitudinal section through agovernon constructed in accordance with this invention, Fig. 2 is atransverse section on line A-A of Fig. 1, Fig. 3 is asimilar section online B-B of Fig. 1, and Fig. 4 is a View similar to Fig. 1 showing amodified construction.

Referring to the drawing, the shaft 1 of the engine enters at one endlinto a pump case 5, within which said shaft has keyed thereto a disk 2,preferably of substantially' square shape, as shown. Said disk carriesa:

number of blades or vanes 3, extending laterally to one side only ofperpendicular diameters of the case, as shown in Fig. 3, these bladesacting upon the fluid which enters the case by means of a tubular inletpassage 5X and an opening 4 in one side wall of the casing. The rotationof the shaft causes the rotation of the impelling disk 2 with its blades3 and the fluid is sucked in through the inlet 5X and is discharged,through the tangential outlet 5y, illustrated in Fig. 8, said outlet,in case the device is used on an` explosive engine, being connected withthe water jacket.

Located within the case 5, and acted upon by the body of fluid therein,is an oscillating adjusting disk 6 arranged with one face in closeproximity to the side wall of the 'case and having upon its oppositeface a series of radially directed ribs or vanes 8, the width of whichincreases toward the periphery of said adjusting disk, viz. said vanesor ribs project farther toward the center of the case at their outerends than at their inner ends. It will be noted that the impeller 2 isbent away from the engine shaft or dished in order to fit within thespace defined by the radial vanes 8, said iinpeller thus rotating inclose proximity to these vanes. The adjusting disk 6 is fixed to the endof shaft or spindle 7 which projects into the case 5 through a hub 12alined with the engine shaft, and at the Outerend of the shaft 7 thesame carries a lever 10, adapted to control the gas intake of theexplosive engine. Said lever has connected to its hub portion a helicalspring 9 which embraces the hub 12 vand is connected at its opposite endwith an adjusting lever 11 adapted to be angularly displaced on the hub12 by means of a circular portion or sleeve fitting over said hub asshown in Fig. 1, said lever being adjustably clamped in position on thehub by means of a set screw 13.

It is obvious that the adjustment of the lever 11 controls, through thespring connections described, the position and movement of the lever 10with which the adjusting disk 6 is connected. Wvhen the device is in useand the fluid is being pumped out of the case 5 the rotating body offluid within the case, impelled by the iinpeller, will act on the vanes8 of the adjusting disk and move the latter in the direction in whichthe fluid is flowing. This movement of the adjusting or controlling diskvaries in amplitude according to the force exerted by the iinpeller onthe fluid, that is to say, such movement of the adjusting diskcorresponds with the speed of the engine, and as the controlling lever10 is in fixed relation with said disk, said lever will be operated tocontrol the gas intake in correspondence with the speed of the engine,the gas being admitted in exactly the amount called for by theconditions which exist at any particular moment. It will be understoodthat the movement of the controlling disk by the body of fluid isopposed by the spring 9, which prevents the controlling disk from havinganything but a limited angular movement. Thus the device not only causesthe proper circulation of the water, in the explosive engine, but italso effectively controls the fuel supply at the same time.

lVhen it is necessary to adjust the apparatus and place the adjustingdiskl in any particular' position it is only necessary to loosen the setscrew 13 and after angularly adjusting the lever l1 to the requiredextentof the governor is correspondingly increased.

This arrangement, however, can only be used in engines when there is nocirculation of liquid by means of a pump, and hence it is not adaptedfor use in explosive engines in the manner pointed out above.

lVe claim l. In a governor or speed regulator, the combination of a pumpcase, an impeller rotatable in the case, an inlet through which fluid issucked into the case by the impeller, an outlet through which fluid ispumped out of the case, and an adjusting disk in the case which is movedangularly through different distances by the rotating body of fluid.

2. In a governor or speed regulator, the combination of a pump case, animpeller rotatable therein, an adjusting disk Within the pump case andhaving an exteriorly projecting shaft, a controlling lever mounted onsaid shaft, and means to vary the initial position ofsaid controllinglever.

3. ln a governor or speed regulator, the combination of a pump case, animpeller rotatable therein, an adjusting disk Within the case and havingan exteriorly projecting shaft, a controlling device mounted on saidshaft, a spring surrounding the shaft and connected with saidcontrolling device, and an adjusting device to which said spring isconnected.

et. In a governor or speed regulator, the combination of a pump casehaving a hub, an impeller rotatable in the case, an adjusting diskmounted to turn angularly Within the case and having an exteriorlyprojecting shaft journaled in said hub, a controlling lever on saidshaft exteriorly of the case, a spring embracing the hub and connectedat one end with said lever, and an adjusting lever to which the oppositeend of the spring is connected and which is angularly adjustable ugousaid hub.

ln a goif'ernor or speed regulator, the combination of a pump ease, anadjusting or controlling disk mounted to turn angularly within the caseand having exterior connections, radial ribs or vanes on said diskincreasing in width from the inner portion of the disk toward theperiphery, and a dishcd impeller Within the case conforming to androtatable in the space defined by said ribs or vancs.

G. in an explosive engine, the combination of a centrifugal pump whichkeeps up the Water circrdation, and an engine controlling deviceincluding a member within the pump case acted on by the body of vatertherein.

7. The combination of a pump case, an impeller rotatable in the case, aninlet through which fiuid is sucked into the case by the impeller, anoutlet through which fluid is pumped out of the case, and anengine-colitrolling member Within the pump case and operated by contactwith the rotating body of fluid therein.

In testimony whereof We affix our signatures, in presence of twowitnesses.
